Q.    A man traverses a street in 6 minutes, walking at a speed of 4 km/h. Find the length of the street.
 

Dear student,  

The chapter you have tagged is not according to question. However the solution is provided below:-

$$\begin{gathered} We have, \\ Time=6 minutes=\frac{6}{60} hr=\frac{1}{10}hr \\ Speed=4 km/hr \\ Dis\tan ce= Speed\times Time \\ =4\times \frac{1}{10} \\ =\frac{2}{5} km \\ =\frac{2}{5}\times 1000m \\ =2\times 200m \\ \Rightarrow Dis\tan ce=400m \\ Thus the length of the street is 400m. \end{gathered}$$
